Abstract

Patente de Invenção: <B>MONTAGEM DE UMA CONEXãO DE PONTA E DE UM TUBO FLEXìVEL"<D>. Uma montagem (8) de uma conexão de ponta (9) e de um tubo de pressão flexível (1), de uma estrutura não-ligada e que compreende diversas camadas (2, 3, 4, 5, 7) incluindo pelo menos uma camada (5) tendo vários fios blindados de tensão, metálicos, chatos, enrolados no sentido helicoidal (6) com conexões de ponta que, na condição montada, são incrustadas em uma âncora (23) constituída de um material de fundição, como por exemplo um epóxi, injetado dentro de uma cavidade formada na conexão de ponta. As partes de ponta de fio chato têm pelo menos uma torção (25) que gira de modo geral em torno da linha de centro do fio. As ditas torções travam os fios blindados de tensão firmemente na âncora e dessa forma provêm uma resistência maior às cargas de tensão axiais que atuam na montagem do que antes conhecido. Além disso, a junta é uma estrutura simples e barata e pode ser feita no local.Invention Patent: <B> ASSEMBLY OF A TIP CONNECTION AND A FLEXIBLE TUBE "<D>. An assembly (8) of a tip connection (9) and a flexible pressure pipe (1), of a structure non-bonded and comprising several layers (2, 3, 4, 5, 7) including at least one layer (5) having several flat, shielded tension wires, metallic, wound in a helical direction (6) with end connections that , in the assembled condition, are embedded in an anchor (23) made of a casting material, such as epoxy, injected into a cavity formed in the tip connection. The flat wire tip parts have at least one twist ( 25) which generally rotates around the center line of the wire, said twists lock the tension armored wires firmly on the anchor and thus provide greater resistance to the axial tension loads acting on the assembly than previously known. addition, the joint is a simple and inexpensive structure and can be made it's on the spot.
